European Momentum Strategies, Information Diffusion, and Investor Conservatism

EUROPEAN FINANCIAL MANAGEMENT, Issue 3 2005
John A. Doukas
G1; G11; G14 Abstract In this paper we conduct an out-of-sample test of two behavioural theories that have been proposed to explain momentum in stock returns. We test the gradual-information-diffusion model of Hong and Stein (1999) and the investor conservatism bias model of Barberis et al. (1998) in a sample of 13 European stock markets during the period 1988 to 2001. These two models predict that momentum comes from the (i) gradual dissemination of firm-specific information and (ii) investors' failure to update their beliefs sufficiently when they observe new public information. The findings of this study are consistent with the predictions of the behavioural models of Hong and Stein's (1999) and Barberis et al. (1998). The evidence shows that momentum is the result of the gradual diffusion of private information and investors' psychological conservatism reflected on the systematic errors they make in forming earnings expectations by not updating them adequately relative to their prior beliefs and by undervaluing the statistical weight of new information.

Momentum investing and the asset allocation decision

ACCOUNTING & FINANCE, Issue 4 2007
Karen L. Benson
G23 Abstract This study examines the active asset allocation decisions of Australian multisector fund managers to determine whether active fund managers engage in momentum strategies. We find evidence supporting the existence of momentum investing in active asset allocation strategies. This evidence exists in the Australian Equities, Australian Fixed Interest and Listed Property asset classes. Interestingly, balanced funds adopt contrarian strategies in the International Equities asset class. We also examine whether there is any association between a fund's market timing skill and the execution of momentum strategies. Our results show that fund managers with no market timing skill are momentum investors. [source]

The Behavior and Performance of Foreign Investors in Emerging Equity Markets: Evidence from Taiwan

INTERNATIONAL REVIEW OF FINANCE, Issue 3-4 2003
Anchor Y. Lin
This study investigates trading behavior and investment performance of foreign investors in 60 large-size firms listed on the Taiwan Stock Exchange. Strong evidence is found that foreign investors employ momentum strategies of buying past winners and selling past losers and favor large-size, high book-to-market, and high-tech stocks, while no evidence is found that foreign investors herd on market consensus. Findings show that foreign investors are short-term superior performers but long-term inferior performers. The short-term superior performance appears to be driven partially by price momentum of winners portfolios rather than by risk taking. After controlling for firm size, share turnover, and industry, foreigners' short-term performance in large-size, high-turnover, and high-tech stocks is better than it is in small-size, low-turnover, and non-high-tech stocks.

Individualism and Momentum around the World

THE JOURNAL OF FINANCE, Issue 1 2010
ANDY C.W. CHUI
ABSTRACT This paper examines how cultural differences influence the returns of momentum strategies. Cross-country cultural differences are measured with an individualism index developed by Hofstede (2001), which is related to overconfidence and self-attribution bias. We find that individualism is positively associated with trading volume and volatility, as well as to the magnitude of momentum profits. Momentum profits are also positively related to analyst forecast dispersion, transaction costs, and the familiarity of the market to foreigners, and negatively related to firm size and volatility. However, the addition of these and other variables does not dampen the relation between individualism and momentum profits. [source]

Are Momentum Profits Robust to Trading Costs?

THE JOURNAL OF FINANCE, Issue 3 2004
Robert A. Korajczyk
We test whether momentum strategies remain profitable after considering market frictions induced by trading. Intraday data are used to estimate alternative measures of proportional and non-proportional (price impact) trading costs. The price impact models imply that abnormal returns to portfolio strategies decline with portfolio size. We calculate break-even fund sizes that lead to zero abnormal returns. In addition to equal- and value-weighted momentum strategies, we derive a liquidity-weighted strategy designed to reduce the cost of trades. Equal-weighted strategies perform the best before trading costs and the worst after trading costs. Liquidity-weighted and hybrid liquidity/value-weighted strategies have the largest break-even fund sizes: $5 billion or more (relative to December 1999 market capitalization) may be invested in these momentum strategies before the apparent profit opportunities vanish.

Momentum, Business Cycle, and Time-varying Expected Returns

THE JOURNAL OF FINANCE, Issue 2 2002
Tarun Chordia
A growing number of researchers argue that time-series patterns in returns are due to investor irrationality and thus can be translated into abnormal profits. Continuation of short-term returns or momentum is one such pattern that has defied any rational explanation and is at odds with market efficiency. This paper shows that profits to momentum strategies can be explained by a set of lagged macroeconomic variables and payoffs to momentum strategies disappear once stock returns are adjusted for their predictability based on these macroeconomic variables. Our results provide a possible role for time-varying expected returns as an explanation for momentum payoffs. [source]

MOMENTUM: DOES THE DATABASE MAKE A DIFFERENCE?

THE JOURNAL OF FINANCIAL RESEARCH, Issue 4 2006
Bidisha Chakrabarty
Abstract We examine discrepancies between the Center for Research in Security Prices (CRSP) and Trade and Quote (TAQ) databases by examining the returns of momentum strategies using each database. Momentum portfolios constructed from CRSP prices earn significant profits whereas similar portfolios using TAQ prices show losses. Adjusting TAQ prices with the TAQ dividends file or with the cumulative distribution factor provided by CRSP does not eliminate all differences. There are significant discrepancies in the way CRSP and TAQ record newly listed and delisted stocks. We document the residual (after all filters) price differences between the two databases and provide filters to adjust TAQ data for long sample periods and large sample sizes. Our filtering procedures allow for the possibility of examining intraday patterns in momentum profits. [source]

An examination of momentum strategies in commodity futures markets

THE JOURNAL OF FUTURES MARKETS, Issue 3 2007
Qian Shen
Commodity futures and equity markets differ in several important respects. Nevertheless, it was found that momentum profits in commodities are highly significant for holding periods as long as 9 months, and returns to momentum strategies are roughly equal in magnitude to those that have been reported in stocks. The profits documented are too large to be subsumed by transactions costs. Although the momentum strategies appear to be quite risky, their profitability cannot be fully accounted for in the context of a market factor model. Further, it is shown that momentum profits eventually reverse if positions are maintained long enough after portfolio formation. © 2007 Wiley Periodicals, Inc. Jrl Fut Mark 27:227,256, 2007 [source]
